FUE -MI IN ATTACHMENT.

Application filed October 20, 1922. Serial No. 595,789.

To all whom it may concern:

Be it known that I, SoIrIo S. GENTILE, a citizen of the United States, residing at 1321 Main Street, 'Vicksburg, in the county of 5 lVarren and State of Mississippi, have invented certain new and useful Improvements in a Fuel-Mixing Attachment, of which the following is a specification.

This invention relates to, a fuel mixing attachment or interceptor for internal combustion engines and has for its particular object to provide means for causing an intimate mixing of the air and gas prior to its admission into the combustion chambers of the engine.

The invention relatesigenerally t0 the type of apparatus described and claimed in my pending application Serial.No.' 569,933 filed June 21st, 1922. I

[The particular objectof this invention is to provide a fuel mixingattachment or in terceptor designed for use on heavy duty motors but the advantageous results are attainable also when this device is used in connection with an internal combustion engine. It is customary to'provide fan shaped propellers and to position these propellers or interce-ptors in the path of the fuel as it is conducted from the carburetor to the in- 9 take manifold of the engine. However despite the fact that the purpose of these propellers was to cause an intimate'intermixing of the fuel and air they failed in their purpose because particles; of fuel and air escaped between the blades of the propeller and entered the intake manifold relatively separate. I

In the construction described and mentioned in my pending applicationabove referred to a construction was described wherein under ordinary circumstances a satisfactory intermixing of the air andfuel was accomplished. However it 'has been found by experiment that heavy duty engines require a still more efficient intermixing of the fuel and air and to this end this present invention is designed to' provide an interceptor or fuel mixing attachment which will work stances. 1

The novel combination and construction of parts of my invention will be made more apparent as the'description proceeds, especially when consideredin connection with the accompanying drawings wherein:

V 7

Referring now more particularly to the drawings wherein like reference characters indicate like parts, itwill bejnoted that there is illustrated a portion ofa carburetor 10 and an intake manifold 11 between which parts my invention is adapted to be inter posed. A jacket 12 is provided with flanges 18 at-hoth ends thereof whereby connection may be made with the carburetor and intake manifold by means of bolts 14.

For the purposeof mounting the interceptor within the jacket thereis preferablyv provided gaskets 15 such as illustrated in Fig. 3, each gasket being provided on one face with a circumferential groove 16, spider arms 17 being provided formounting the central. shaft 18 of the interceptor as clearly illustrated in Fig. 1 e The interceptor is assembled on the shaft 18, there being arranged in the order named a .lower nut '19, a collar 20, a lower set of propeller or interceptor blades 21, anintermediate collar 22, an upper setlof inter ceptor or propeller'blades 23, an upper collar 2e and an upper nut 25. Ball bearings '26 areprovidedso that the propeller blades may .rotate freelyabout the shaft 18. The propeller blades are similar in construction tofthose illustrated and described in my 7 pending application above referred to, and 10 are each provided with an inclined blade portion 27, a horizontal blade portion 28 and an overlapping blade portion 29, which overlies the blade portion 28 of the next. succeeding blade. In this manner the pas- 105 sag'eway through the jacket 12 past the in- I terceptors is materially blocked. I In addition to the interceptors there is provided in this present instance one or more layers of wire gauze 30 which completely cover the top of each interceptor and closely surround the associated central collar. This wire gauze is bent down around the periphery of each set of interceptors and is secured in place by a collar 31 surrounding each set of inte-rruptors adjacent the top thereof, this collar being welded or otherwise securely fastened to the interceptor blades where it engages the same. The wire gauze is bent up around the lower edge of each collar 31 and secured thereto as at 32 by welding or brazing the same.

To positively direct the air and fuel into engagement with the lower interceptor there is provided a second collar 33 which adjoins the collar 31 of the lower interceptor and extends upwardly to a point within the circular slot 16 of the lower gasket 15. In this manner air and gas is directed into intimate contact with the lower interceptor which operates to intimately intermix the same.

The upper interceptor. is not provided with the supplemental collar 33 but the upper edge of the collar 31 engages in the circular slot 16 formed in the upper gasket 15. In this manner the air and gas is positively directed through the upper pro-' peller before it passes into the intake manifold.

Obviously therefore the fuel is positively mixed because as it passes through the jacket 12 the force of the same causes the propellers to revolve, these propellers revolving in opposite directions because of the pitch of the blades. Obviously the wire gauze revolves with their associated propellers and the fuel 1 and air passing therethrough are consequently thoroughly mixed.

Inasmuch as the entire value of the fuel is obtained the mixture delivered to the carburetor is considerably richer than with a corresponding adjustment of the carburetor where this interceptor is not used and in order'to re-establish the proper portion of air and gas there is provided a supplemental air inlet 34 which communicates with the jacket 12 as at 35 adjacent the lower end thereof. This auxiliary air inlet is provided with a spring controlled ball valve 36 and a manually operated valve 37 which can be controlled from the instrument board of the motor vehicle. Obviously by opening the valve 37, the suction willunseat the ball valve 36 against the action of the. spring and will permit a charge of air to enter into the jacket 12 in proportion to the amount the valve 37 is opened.

Obviously this air mixes with the charge of air and gas already passing through the jacket 12 and in this manner the proper ratio of air and gas is re-established and delivered to the intake manifold.

In some instances it may be found desir- 'of the internal combustion type.

able to eliminate the gaskets 15 and in such a case the coupling flange of either the carburetor or the intake manifold is provided with a circular groove 38 in the manner illustrated in Fig. 6. Either or both the flanges of the intake manifold and carburetor may be grooved thus eliminating either one or both of the gaskets 15. Obviously, the same purpose is accomplished, that is, the fuel is positively directed into engagement with the interceptors.

However, in such a case it becomes necessary to provide supporting means for supporting the shaft 18 of the interceptor and for accomplishing this, separate supporting spiders 39 are provided which are secured in position in the manner clearly illustrated in Fig. 6.

From the foregoing itwill be immediately apparent that a practical and eflicient arrangement is provided whereby the raw gasoline is broken up and thoroughly and efficiently mixed with the air and that furthermore, means are provided whereby the ratio of air and gas may be re-established when the occasion demands and a proper mixture'delivered to the intake manifold of the engine.

As mentioned hereinbefore while this arrangement is designed particularly for heavy duty motors it is practical and eflicient for any type of motor vehicle engine The construction of the interceptor is such that it may be conveniently secured in position and the rotary parts of the interceptor may be dissembled and parts replaced when the occasion demands;

All the parts are made of rust-proof material so as to prevent erosion and the consequential deterioration of the parts.

Obvious modifications will suggest them-- selves to those skilled in the art and to this end I make reservation to make such changes of form and construction as may be within the limits of mechanical skill and as may come within the purview of the accome panying claims.

Having thus what I claim is: I
